Eureka Environmental has thousands of Manta Multiprobes in the field used for a myriad of applications. 

Ideal for:

  • Spot checking 

  • Profiling

  • Low flow sampling

  • Lab use

  • Wireless communication to cable reels

Battery life

A fully charged mantaMobile device will run up to 22 continuous hours (based on operating a Manta+ multiprobe with 13 sensors). Run time increases with fewer sensors; will vary depending on the type and number of sensors installed.

How does it work?

The mantaMobile connects to the multiprobe’s underwater cable, any length up to 200 meters. It provides power to the probe, and a wireless connection to a Bluetooth-enabled display. Eureka’s mantaLink App for the display device provides control features, including sensor configuration, instant and automated data capture, file management, calibration, GPS, geofencing, and more! Data files may be emailed for convenience.

Manta link app

You must first download the mantaLink App to your display, from the Google Play Store, or Apple App Store. Once paired with the mantaMobile Bluetooth device, launch the App to connect to a Eureka multiprobe.



Trimeter and Manta Probes are multiparameter sondes for monitoring water quality in fresh, brackish and marine waters.  All sondes may be used for discrete sampling, profiling, as self-powered loggers, or connected to telemetry stations for continuous real-time monitoring, with water quality data accessible via cloud-based software.  Our sondes communicate RS-232, SDI-12 or Modbus, for flexibility in connecting to a variety of different data loggers and PLC’s.  Eureka offers the largest selection of water quality sensor technologies in the industry.  So in addition to standard configurations, each probe may be customized for your specific application.  Pick sensors of your choice to fully populate larger probes, or add a battery pack to convert a probe to a logging device.  All Trimeter and Manta probes feature anti-corrosive housings and sensors, robust marine bulkhead connectors, and anti-fouling options.  LED status indicators on each sonde provide important diagnostic information. Each probe includes an industry-leading 3 year warranty.  Operate your Trimeter and Manta probes with a variety of display options, via a direct or Bluetooth connection.  Intuitive control software, available for Windows, iOS and Android is included at no additional cost with every probe.


Eureka’s compact, low cost Trimeter is designed for projects that require the same high-quality features of a Manta+ probe, but fewer sensors.
